QUESTION 2

2.1 – Extract from Assignment Question

The score for the English Placement Test (EPT) is calculated based on the marks obtained from the speaking, listening, and writing tests. The maximum mark for all the tests is 100%. However, to calculate the grade for the EPT, each test has been given a certain percentage as shown in Table 1. After that, the final marks will be calculated, and the final grade is given as shown in Table 2.

Write an Android app that requests a name and marks for each of the student as shown in Figure 1. When the details have been entered, the app will calculate the final marks and grade and show them on the next screen as shown in Figure 2. Create a snapshot video for running the results of the each of the animations. Your answer must also state the links to get the video.
